Introduction of Green Revolution in India:

Green Revolution took place in three different phases in the various regions of the country at different point of time.

First phase of the Green Revolution: This happened from 1962–65 to 1970-73 with the sharp increases in yield in wheat in the north-western region which included Punjab, Haryana and Western Uttar Pradesh.

Second phase of the Green Revolution: This happened from 1970-73 to 1980-83 with the extension of HYV High Yielding Variety seed technology from wheat to rice, this time the technology spread was in Uttar Pradesh, Andhra Pradesh particularly the coastal areas, parts of Karnataka and Tamil Nadu and soon regions like Maharashtra, Gujarat, improved their production too.

Third Phase: Third phase was from 1980-83, to 1992-95 showed very significant and encouraging results. This time Green Revolution spread to the low growth areas like Orissa, West Bengal, Madhya Pradesh, and Rajasthan. During the last phase, Southern region registered higher rate of growth than Northern region. By the end of this phase, the ‘coefficient of variation’ of the output growth levels and yield [per hectare] level between the various states dropped down substantially compared to earlier decades. By the end of the last phase, there was considerable reduction in regional inequality by increase in the prosperity in rural India.
